Eisner (Harald Krassnitzer) and Fellner (Adele Neuhauser) are called to a crystal-clear case: two bodies and a perpetrator who actually alerted the police himself and is waiting for the investigators at the crime scene—complete with the murder weapon, a motive, and a full confession. It appears to be a crime of passion—a cuckolded husband who simply snapped. Everything could have gone so "smoothly," were it not for the fact that the country's most cunning defense attorney had taken on the accused's case—and secured an acquittal. Shortly thereafter, the attorney himself ends up on the autopsy table—and the acquitted man vanishes without a trace. To top it all off, "Inkasso" Heinzi (Simon Schwarz)—an old acquaintance of Moritz and Bibi—shows up once again to put the pair's friendship to a grueling test.
